LTSA[19] is based on the intuition that when a manifold is correctly unfolded, all of the tangent hyperplanes to the manifold will become aligned. It begins by computing the k-nearest neighbors of every point. It computes the tangent space at every point by computing the d-first principal components in each local neighborhood. It then optimizes to find an embedding that aligns the tangent spaces.

。在提取图像特征点的时候采用提取角点的方式，用角点检测与图像的局部自相关函数紧密结合的方法，通过角点分析来判断待检测点是否为角点。(In the extraction of image features: by the way, extracts angular point with corner detection and image of partial autocorrelation function of integrated method, through the corner to judge whether the line to analysis for the corner.)

智能天线MVDR算法，自适应检测DOA，达到优化性能的目的。(The smart antenna MVDR algorithm, adaptive detection DOA, to achieve the purpose of optimizing performance.)

BPSK SYSTEM SIMULATION We simulate the generation of random variables r0 and r1, which constitutes the input to detector.The detector output is compared with the binary transmitted sequence and an error counter is used to count the number of bit errors.
